Description

Device for microdermabrasion and microdermabrasion method

Technical field and state of the art

The present invention relates to a device for the microdermabrasion of the skin in the field of beauty care, for aesthetic care professionals, including non-doctors.

Microdermabrasion is a process of removing a very superficial layer of skin, consisting of dead cells. Microdermabrasion also helps to resurface the skin. Microdermabrasion unifies the complexion and makes the skin look brighter by eliminating dead cells and promoting the natural process of tissue repair. Microdermabrasion is mainly used on the face, the back of the hands, the décolleté, the stretch marks of the breasts, the stretch marks of the belly, the stretch marks of the hips and the stretch marks of the buttocks, but also other areas such as the arms or the thighs especially to improve skin texture, reduce blemishes or densify and tighten the skin.

Microdermabrasion removes, in addition to the stratum corneum and dead cells, the superficial layer of the epithelium, while remaining at a distance from the basement membrane of the epithelium. WO 2006/045149 discloses a device for skin abrasion comprising a vibrating body and an interchangeable tip having an abrasive surface. It reduces the epidermis layer to create a new skin. However, this device is:

unwieldy,

- does not ensure a good hygiene of use,

- does not ensure good contact between the abrasive surface and the skin.

Description of the invention

The invention aims to overcome the drawbacks of the prior art and for this purpose concerns a device for microdermabrasion comprising:

a detachable tip (1 1) comprising at least one abrasive element (1 12), said abrasive element (1 12) being intended to be applied on the surface of the skin,

a body comprising a vibrating means, said vibrating means being adapted for vibrating the body or the detachable tip (1 1),

an end support (12) fixed to the body,

remarkable in that the detachable tip (1 1) comprises a deformable element (1 13) positioned between the abrasive element (1 12) and the tip support (12), said tip detachable (1 1) comprises a protective element (1 1 1) positioned at the end of the detachable tip and said protective element (1 1 1) being in the form of a half-sphere or a half-sphere flattened.

The device improves the comfort of use on the skin and is suitable for use for all areas of the body. The deformable element touches the skin when using the device object of the invention. In addition, the deformable element makes it possible to adapt the abrasive element to the shape of the skin by virtue of its deformation under pressure.

The protective element protects the skin surface from the edge of the abrasive element.

The term "deformable element" denotes an element consisting of a deformable material that returns to its original shape when the constraint applied to it disappears.

The invention is advantageously implemented according to the embodiments described below. The embodiments are to be considered individually or in any technically effective combinations.

According to one aspect of the invention, the deformable element is made of elastomer whose hardness SHORE is between 10 and 30. The hardness SHORE is defined by the standards ISO 868 and 7619 on a scale ranging from 0 to 100, from soft to soft. hard. The hardness depends on the elasticity of the material.

For safety, the hardness is chosen so that too much pressure stops the vibration and has no effect on the skin.

According to another aspect of the invention, in a section plane to the device containing the longitudinal axis of the body and the longitudinal axis of the tip holder, the longitudinal axis of the tip holder and the longitudinal axis of the body form an angle of between 90 ° and 270 °, preferably 135 °. This angle between the detachable tip and the body increases the maneuverability of the object of the invention and the comfort of the user.

According to another embodiment, the device comprises a pivot connection between the tip support and the body of the device, the axis of said pivot connection being contained in a plane orthogonal to the longitudinal axis of the body and passing through a point intersecting the longitudinal axis of the tip support with the longitudinal axis of the body.

The pivot connection orients the detachable tip relative to the body and adapts the device to different grips and skin surfaces.

Advantageously, the body of the deformable element is oval, triangular, polygonal at least five sides or a circle, whose center is drilled to fit the end support. According to a variant of the device according to the invention, the vibrating means comprises a motor driving in rotation an element comprising an unbalance.

According to this latter variant, the device according to the invention comprises means for varying the speed of rotation of the motor between 0 rpm and 12,000 rpm.

According to another variant, the device comprises at least lighting means, in particular a light-emitting diode whose wavelength is between 400 and 900 nm and between its fluence of between 3 and 4 J / cm ² .

According to this last variant, the wavelength is between 570 and 630 nm.

The term LED (Light Emitting Diode) refers to an optoelectronic component capable of emitting light when traversed by an electric current.

The fluence (for example, 3.4 J / cm ² ) ensures a good efficiency of the application of the light emitting diode.

According to another variant, the deformable element comprises a cavity arranged to receive a volume of a creamy material, such as softening cream.

Thus, during use, the cavity is compressed which causes the cream to come out. According to another variant of the present invention, the device comprises sealing means. In this way, the device is cleanable by passing underwater.

According to another variant of the present invention, the abrasive element comprises a fixing means, such as glue or velcro, arranged to hold the abrasive element in position on the deformable element.

Also according to one variant, the abrasive element is a disposable ribbon, arranged to be positioned around the deformable element and a portion of said ribbon is detachable to allow removal of the abrasive element.

According to embodiments, the detachable tip is rotatable about the longitudinal axis of the tip holder.

According to embodiments, the detachable tip is rotated by a rotating means. The rotary means is a motor whose axis of rotation is connected directly or indirectly (for example the axis of the motor is connected to a conical pinion to the detachable tip).

The invention also relates to a microdermabrasion method for non-therapeutic aesthetic care comprising the following steps:

- a) establishment of a detachable tip on the device of the invention, - b) vibration of the abrasive element on the surface of the skin, for a period of 1 to 30 minutes for a surface of the order of 50 to 300 cm ² . Alternatively, the method comprises a step c), after step b), removing the abrasive element and applying a softening cream on the surface of the skin for a period of 2 to 20 minutes.

Thanks to this device, the first session shows an improvement of the skin texture and a better shine for the face. Indeed, the skin texture is immediately refined and the burst stroke is instantaneous. With a sufficient number of sessions (between 5 and 10 start-up sessions and regular follow-up sessions) the results are comparable, and even better than with existing chemical (peeling) or physical (laser) means.

During the microdermabrasion sessions, associated with the massages and a light wave, for the face, the fine wrinkles flatten out and the surface defects of the skin are attenuated. The skin looks younger, smoother and even. Also at the body where the skin appears more, younger, denser, and more toned.

The long-term effects, if the use is recurrent, are:

- an improvement of the skin texture,

- an increase in the level of collagen and cells of the epithelium, so the flexibility, thickness and quality of the skin.

In general, the invention makes it possible to slow down the effects of time on the skin, in depth and to keep a surface skin always "new". It helps to slow down and reduce the appearance of skin-related imperfections, due to the smoothing of the skin that is done. According to another variant, the method comprises a step d) prior to step a), removing the abrasive element from a sealed bag and placing said abrasive element on the detachable tip. In this way, the abrasive element is disposable which guarantees a hygienic use every time. Brief description of the figures

Description of Embodiments of the Invention

The device for microdermabrasion has a dual purpose: microdermabrasion and massage.

In Figure 1, there is shown the device 1 for the microdermabrasion mounted on its base 2. The device 1 comprises a detachable tip 1 1 1l is shown in this figure the external power supply (transformer 6) to the device 1 which feeds the device or a support to the device. This figure also shows an interface 21 which makes it possible to control the device 1 and in particular to vary the vibration.

In an exemplary embodiment, the detachable tip 1 1 is elongated. The transformer 6 (external power supply) can be connected to the base, the support or the device 1 (this variant will be described below).

According to another example of an embodiment, the device comprises:

either an internal power supply, such as a battery, and a command selected from starting or stopping the operation of the motor, a motor speed controller or a command with a predefined speed,

or a base arranged to receive the device, said base comprising an interface selected from starting or stopping the operation of the motor, a motor speed controller or a command with a predefined speed.

In another example, said device comprises either an external power supply connected to the device or to the base.

Also, according to another example, the base is arranged to be fixed to a support by a connection means. The connection means transmits electricity based, so as to electrically power the device, the support comprising a power supply. The connection means also makes it possible to fix the base to the support.

In Figure 2, there is shown a detachable tip 1 1 comprising several elements. At one end of the detachable tip 1 1, it is placed the protective cap 1 1 1. An abrasive element 1 12 makes it possible to use the device for microdermabrasion. The abrasive element 1 12 is adapted to be applied to the surface of the skin.

The abrasive element January 12 is abrasive paper whose grain is between 100 and 600 grains per square meter. The abrasive element 1 12 is positioned around a deformable element 1 13.

In another embodiment, the abrasive element 1 12 comprises fastening means, such as glue or velcro. This fixing means is adapted to hold the abrasive element 1 12 in position on the deformable element 1 13.

The deformable element 1 13 is for example elastomer. This deformable element 1 13 is optimized with a measured density, to make the microdermabrasion and massage phase optimum and comfortable. According to the scale of hardness Shore, the measurement of the elastomer is between 10 and 30, preferably 18.

In another example of the invention, the deformable element 1 13 has a cream contained in cavities. These cavities can receive a certain volume of a cream, such as regenerative cream, soothing, astringent ...

In Figure 2, it is also shown the rigid center 1 14 which is adapted to be positioned on the tip support 12. The detachable tip 1 1 is positioned on a tip support 12 of the device 1. The rigid center 1 14 is hollowed in its center in the form of the tip holder 12. As shown in Figure 2, the tip holder 12 is of cylindrical shape, so the rigid center has a cylindrical bore. Alternatively, the tip holder 12 may be square-shaped or have a flat surface to better transmit the vibration. The rigid center 1 14 has a shape opposite to the end support 12.

It is also possible that the rigid center 1 14 and the deformable element 1 13 is bi-injected so as not to be able to dissociate the rigid center 1 14 of the deformable element 1 13.

In another embodiment, the protective element 1 1 1 and the deformable element 1 13 are integral with each other.

The protective element 1 1 1 protects the patient from the application of the tip on his skin. It also prevents the edge of the abrasive element January 12 from hurting the patient. For example, the protective element 1 1 1 is in the form of a half-sphere or a flat half-sphere as shown in FIG.

In an exemplary embodiment, the protective element is in the center position on the endpiece. The protective element has a relatively smooth surface condition to avoid injuring the patient.

FIGS. 3 and 4 show the interlocking step of the detachable tip on the tip support 12. It is shown the rigid center 1 14. The rigid center 1 14 allows to fit the detachable tip 1 1 on the end support 12. During nesting (not shown), a ring or a pin breaks to prevent reuse. This interlocking makes it possible to fix the detachable tip 1 1 integrally to the device 1, so as to transmit the vibrations of the device 1 during its operation. For example, the detachable tip 1 1 is inserted and rotated to connect with a position blocker. The fact of making such a movement, will generate a noise to warn the user of the setting in position and maintenance of the detachable tip 1 1 to the device 1. In this way, it is guaranteed a single use to ensure the quality of the tip while respecting hygiene and safety.

Before installing the detachable tip 1 1 on the bit holder 12.

The detachable tip 1 1 is contained in an airtight bag. In this way, hygiene is guaranteed until the bag is opened.

Figures 5 to 7 show a step of removing the abrasive element 1 12. For example, the abrasive element is an interchangeable ribbon arranged to be positioned around the deformable element 1 13. The ribbon is detachable to allow removal abrasive element. For example, the ribbon includes a tab. The tongue may be along its entire length or twisted around the abrasive element 1 13, as shown in FIG. 8. In a variant, there is only the element abrasive which is changed, the deformable element 1 13 and the rigid center 1 14 remain positioned on the tip support 12.

At first, it is necessary to locate the tab. In a second step, it is proceeded to the removal of the tongue to remove the abrasive element January 12 of the detachable tip 1 January. The goal of this step is to move from the microdermabrasion stage to the massage stage. The microdermabrasion step is performed by the abrasive element 1 12 and the massage step is performed by the deformable element 1 13. The deformable element 1 13 is used for the massage phase.

According to a variant, the various elements of the device 1, such as the detachable tip 1 1, are made by injection bioplastic (bio-sourced plastic, biodegradable, compostable ...). In this way, the fact of using a stain remover 1 1 (single use) allows to recycle.

Figures 9 and 10 show different forms of the detachable tip 1 1 in perspective. The deformable element 1 13 integrally mounted to the rigid center 1 14 has the shape of an oval, a triangle, a square, a polygon of at least five sides or a circle. In these figures it is shown that the deformable element is integral with the rigid center 1 14. In this way, the transmission of vibrations is ensured.

FIG. 11 represents the various elements of the device 1. It is represented the end support 12 which cooperates with a motor 13.

The motor 13 rotates a vibrating means, such as a mass eccentric to the axis of rotation of the motor to create the vibration.

In an exemplary embodiment, a switch 14 makes it possible to vary the control of the motor 13. In another example, the interface 21 on the base 2 can vary the speed of rotation of the motor. In an exemplary embodiment, a switch 14 makes it possible to start and stop the motor. A cover 14 covers the tip support 12. The cover 15 does not cover the tip support so that it can receive the detachable tip.

In a variant, the cover is provided with a light, such as an LED, which can vary from a light of the order of 400 to 900 nm, preferably of the order of 570 to 630 nm. In a variant, an LED is positioned on each side of the cover 15. In another variant, the cover has an LED only below. In another embodiment, an LED is positioned above the cover 15.

Clinical trials use sufficiently penetrating wavelengths around 600nm or in the infrared, fluences (delivered dose) of 1 to 20J / cm ² and irradiances (density of power or intensity) varying according to the distance the light source and spot size from 5 to 50mW / cm ² .

The photo-biological effects depend on the choice of the parameters of the irradiation: the wavelength, the delivered dose (fluence), the irradiance (density of power or intensity), the irradiation time (exposure time), the continuous delivery mode or pulsed with possible combinations (pause time / pause time) to infinity for the latter mode.

In another embodiment, the LEDs illuminate the underside and sides of the detachable tip. In this example, there is no LED on it because the tip stain would hide the light beam.

The device uses several wavelengths of light.

In an exemplary embodiment, the interface 21 or the device 1 has three buttons for selecting three colors, such as yellow at 588 nm, orange at 601 nm and red at 628 nm.

Still in Figure 1 1, it is shown an overmolding of the cable 17 which facilitates the handling of the device 1 by preventing the cable 17 from falling back on the device 1. The overmolding makes it possible to have a rounded shape of the cable 17.

FIG. 12 shows an angle α between the longitudinal axis A of the detachable tip 1 1 and the longitudinal axis B of the device 1.

The longitudinal axis A of the detachable tip 1 1 (as shown in the figure) is defined at the intersection of the "horizontal plane" of the detachable tip 1 1 defined in the usual sense in the terrestrial reference and the "plan transverse "defined along the axis perpendicular to the horizontal plane.

The longitudinal axis B of the device 1 (as shown in the figure) is defined at the intersection of the "horizontal plane" of the device 1 defined in the usual sense in the terrestrial reference and the "transverse plane" defined along the perpendicular axis in the horizontal plane.

As shown in Figure 12, the angle α is 135 °.

In a variant of the invention, FIG. 13 represents the angle α at 90 °. In the same variant, it is possible to have an angle α at 270 °. Indeed, in this variant, the angle may vary from 90 ° to 270 °. The device 1 is connected to the detachable tip 1 1 by a pivoting element. A pivot connection is disposed between the tip holder 12 and the device 1 (or the body of the device as shown in this figure). The pivot connection passes through an axis of rotation contained in a plane orthogonal to the longitudinal axis of the body of the device 1 and passing through a point of intersection of the longitudinal axis of the end support and the longitudinal axis of the body. .

In a variant, the pivot connection is locked to maintain the position at a preferred angle α. In this way, the device makes it possible to adapt to the treatment areas where the skin is difficult to access.

In Figure 14, the angle α is 180 °. In this position, the longitudinal axis A of the detachable tip 1 1 and the longitudinal axis B of the device 1 are merged. Figure 15 shows the vibrating means in the tip holder. The motor 13 is positioned along the longitudinal axis B of the device 1. The vibrating means causes oscillation of the end support 12 according to the rotation frequency of the motor 13.

As the detachable tip 1 1 is secured to the tip holder 12, the vibration of the tip holder 12 causes the vibration of the detachable tip 1 January.

As specified above, the device 1 or the base 2 has a control of the setting vibration (which corresponds to the start of the motor 13).

When the device is equipped with a switch 14, it can act on the vibrating means (vary the speed of the motor) from 0 rpm to 12,000 rpm. Preferably, two preprogrammed speeds are provided, a first speed of 6000 rpm and a second speed of 3000 rpm. The speed of 6,000 rpm corresponds to the microdermabrasion phase and the speed of 3,000 rpm corresponds to the massage phase. The switch also turns off the device.

When the device does not have a switch 14, the control can be done via the interface 21. The interface 21 has both speeds and / or a variable speed drive.

It is also possible to have in another variant, all the controls of the interface 21 are found on the device 1. Thus, the user can choose whether to use the commands of the interface 21 or the device.

In Figures 16 and 17, there is shown a variant of the device with air drawn from a treatment zone 5. In this way, the air expels the dead skin from the treatment zone 5 during operation of the device . Figure 17 shows the air outlets 4.

It is also possible to have a waterproof device. In this way, the device can be cleaned with water. Elastic joints make it possible to create this seal and are found on the various elements of the device 1, in particular the shell.

Figure 18 shows another variant of the invention. The device 1, as shown, comprises an internal battery that can be recharged directly by a transformer 6. The connection is made at one end of the device 1 and can recharge and / or power the device 1.

Figure 19 shows an exploded view of the device 1. It is also shown the interface 21 and the base 2. This figure also shows, an accessory tray 3.

The accessory tray is fixed with two or four screws on the base 2.

FIG. 20 shows another embodiment of an embodiment in which a cable 17 is positioned in a cable guide. The cable guide is cylindrical and comprises a groove in which the cable 17 is positioned. FIG. 21 shows the connection means 22. The connection means 22 is in the form of a disk and comprises bayonets to allow a locking of its position in the base 2. The base 2 shows that the bayonets make it possible to ensure the blocking in position. Said position may allow an electrical connection. To remove the base 2 from its support, it is necessary to turn a quarter turn to remove the bayonets from their housing.

Figures 22 and 23 show the location of the LEDs on the side of the device 1. In this way, the LEDs illuminate at least the entire length of the detachable tip 1 1 and the sides of the detachable tip 1 1.

The dimensions of the tip may vary depending on the use. For microdermabrasion, the length of the detachable tip 1 1 may be of the order of 15 to 45 mm, preferably 25 mm for the face and 35 mm for the body. For the massage, the length of the detachable tip 1 1 may be of the order of 15 to 45 mm, preferably 25 mm for the face and 35 mm for the body.

Figure 24 shows a histological section of the skin of a patient before application of the device 1. It is shown the ambient air 7, the stratum corneum 8, the epithelium 9, the basement membrane 100, the dermis 101, the collagen 102 and the microvasculature 103. Before a first application, the skin is covered with a regular epithelium . The very superficial dermis 101 is quite loose. It contains some vessels and rare mononuclear inflammatory cells.

After two sessions of microdermabrasion, the epidermis appears a little modified. It is a little thickened with an increase in the number of keratinocytes of about 10%. In the superficial dermis, there is a more fibrous appearance in the most superficial collagen. The vessels are more numerous as are the mononuclear inflammatory cells.

After four sessions and massages, the epidermis is thickened by about 20% compared to an untreated area. Densification of the superficial dermis is maintained as is neovascularization.

Figure 25 shows a histological section of a patient's skin after four sessions of microdermabrasion and massage with a cream. It is also shown the ambient air 7, the stratum corneum 8, the epithelium 9, the basement membrane 100, the dermis 101, the collagen 102 and the microvasculature 103. The epidermis appears increased in thickness. It is appreciated at 25%. Superficial collagen also appears denser. Microvascularization persists.

Microdermabrasion causes thickening of the epidermis with inflammatory fibrosis of the superficial dermis. These aspects are increased with the number of sessions. The application of the cream with massage amplifies the similar effects of the treatment.

It has been noted that sensitive skin may be prone to mild skin dryness within three days of treatment. The pores are tightened and the skin standardized, these effects last up to three weeks.

The following example concerns the protocol of use of the microderm abrasion process.

For the face :

The patient is lying down (or slightly raised). The patient is cleansed so that all creams can be removed. The skin must be as pure as possible to have the maximum benefit of the microdermabrasion phase. The face is then washed (there is no recommended soap, but it is recommended a non-allergenic soap, neutral pH) and rinsed. The skin must not be wet anymore. Dry skin ensures optimal microdermabrasion efficiency.

A first step of the process is therefore a phase of preparation of the skin, cleaning and drying. This step can take three to four minutes.

Regarding the microdermabrasion stage.

Its goal is to shape the skin to improve skin texture, reduce fine lines, reduce stretch marks, anticipate the effects of time on the skin, slow the appearance of imperfections and slow the appearance of irregularities related at the time by a smoothing of the skin.

In an exemplary embodiment, the microdermabrasion step is associated with a light wave (4 seconds for each color, in rotation, yellow-orange-red).

The device is arranged next to the patient. The microdermabrasion step is to take the device as a pencil, being careful not to clog the LEDs with your fingers. It is necessary to install beforehand a detachable tip on the device.

Then it is necessary to put the device in microdermabrasion mode and proceed to microdermabrasion. For the face, it is possible to proceed in the following order: 1 / the right cheek, 21 the left cheek, 3 / the surface within the nasogenian folds (chin, lower lip, upper lip), 4 / nose and 5 / Forehead. Do not go over the eyes and eyelids or the red part of the lips.

In another example, the abrasive element January 12 has 5 facets. It is the facet of the bottom which acts during the setting in function in microdermabrasion mode. Thus, by a rotation system can rotate the detachable tip 1 1 and choose another facet of the abrasive element 1 1 2 treatment: each facet corresponds to about a treated area of 50 to 150 cm2. For the face, every facet will be used for a zone: treat the right cheek, then turn the tip and use a new microdermabrasion facet for the left cheek, then turn the tip and use a new facet for the set chin / white lip lower and upper lip (avoiding the red area of the lip), so on for other areas (the face is divided into 5 areas, and each area will be treated by one of the facets of the tip).

To apply the detachable tip on the skin, it must just be placed so that the harmless friction (abrasion stops automatically when the pressure is stronger, because of the flexibility of the skin that starts to vibrate ). The gesture can be to make circles in the direction of the clockwise, so we treat each time a "disc of three cm in diameter", twelve passages per disc, speed: one second per turn (it is a round in one second).

It is twelve rounds on the spot (discs) three cm in diameter in the direction of clockwise, at the speed of a round per second approximately. In other words, each color lasts 4 seconds, so a color cycle (Yellow, orange red) lasts 12 seconds (then another yellow, orange, red cycle starts again), the user makes about 4 rounds in the same place for each color, which gives 12 rounds for the same disc in 12 seconds. In all cases, at the end of a color cycle, the manipulator proceeds to the treatment of the neighboring skin by treating a disk on the adjacent area.

For example per cheek it is planned ten to twelve disks is about 120 seconds (2 minutes), for the chin, lower and upper lips = five disks is about a minute, the nose = five disks or about a minute and the front = ten twelve discs, about 120 seconds (2 minutes).

The stage of the microdermabrasion procedure for a face is about eight minutes.

A variant at the technical level is (instead of processing disks) to go back and forth on a linear zone 4 cm long, the width of the detachable tip 1 12, each go (or return) for about one second, two round trips per color, or six round trips per color cycle on the same zone, and change zone at the end of a color cycle (which gives six roundtrips, or twelve rounds per zone treated ).

Once the user has finished treating one of the large areas of the face (eg the right cheek), the user turns the detachable tip and then positions a new facet. The user will do the same for the left cheek, and for the other zones.

Following the microdermabrasion, it is carried out a cleaning step that removes all the impurities and dead skin or imperfections that have been smoothed by the device. It is possible to perform this cleaning by passing a wipe, which takes about a minute.

The massage step, corresponding to the massage phase by the deformable element makes it possible to improve the quality of the skin in terms of epidermis, vascularization and production of collagen fibers. This step allows a better impregnation of the cream on purified skin, smoothed and exposed by microderm abrasion.

The massage stage consists of applying a regenerating, soothing, astringent cream. This step consists of applying the cream to an area of the face, do not hesitate to add if the feeling of slipping is not enough.

It is necessary to switch to "massage" mode. It is necessary to remove abrasive element and place the deformable element on the face with the same order of passage as for the microdermabrasion step.

From a technical point of view, it is the same as for the microdermabrasion phase except that the duration is longer (for example doubled) depending on the type of care performed (ex: 8 to 16 minutes depending on duration of care for a face). Then a complete cleaning is done (washing with soap, advising a non allergenic neutral soap), then rinsing and drying, which can take 3 to 4 minutes.

An alternative to the method is to treat only one area of the face (eg chin, upper and lower lips).

For the rest of the body, the procedure is the same with the following variables: - we will use a mouthpiece "body" to larger grain (180 g / m2) (against 400 g / m2 for the face);

- the larger number of passages, for example, two color cycles, ie 24 seconds of treatment per disc, except for the more sensitive areas (hands, inner thighs, around areolas) for which one can stay at 12 seconds is a single color cycle per treated disc;

- the treated surface (whole face = between 200 and 300 cm2) = for the body, with the tip "body" can be treated up to 400 cm2, but if the treated surface is larger, it will take a second mouthpiece . Nomenclature
